- Key Clinical Message Inherited conditions associated with thrombocytopenia should be included in the differential diagnosis of young patients with refractory immune thrombocytopenia (ITP), even in the absence of a positive family history. Early identification of such conditions is of vital importance in order to reach the right diagnosis and avoid unnecessary or even harmful medication.

Tidskriftsartikel (refereegranskat)abstract
- The introduction of minimal residual disease (MRD) monitoring, in the Swedish national guidelines for acute lymphoblastic leukaemia, was evaluated in 35 patients aged 46-79 years (median 61), who were diagnosed from 2007 to 2011 and treated with high-intensity, block-based chemotherapy (ABCDV/VABA induction). Both a high complete remission rate (91 %) and acceptable overall survival (OS) rate (47 %) at 5 years were achieved. MRD by flow cytometry was measured in 73 % of the patients reaching complete remission after the first course, but was omitted by the clinicians for eight patients who were either over 70 years of age or already met conventional high-risk criteria. Factors negatively influencing OS were age over 65 years and WHO status >= 2. MRD < 0.1 % after induction had positive impact on continuous complete remission but not on OS. Only five patients were allocated to allogeneic haematopoietic stem cell transplantation in first remission, mainly due to conventional high risk factors. Thus, use of intensive remission induction therapy is effective in a selection of older patients. In a population for whom the possibilities of treatment escalation are limited, the optimal role of MRD monitoring remains to be determined.

- Follicular lymphoma is commonly transformed to a more aggressive diffuse large B-cell lymphoma (DLBCL). In order to molecularely characterize this histiological and clinical transformation, comparative genomic hybridization was applied on 23 follicular lymphoma and 35 transformed DLBCL tumors from a total of 30 patients. The results were also compared with our published findings in de novo DLBCL. Copy number changes were detected in 70% of follicular lymphoma and in 97% of transformed DLBCL. In follicular lymphoma, the most common alterations were +18q21 (33%), +Xq25–26 (28%), +1q31–32 (23%), and -17p (23%), whereas transformed DLBCL most frequently exhibited +Xq25–26 (36%), +12q15 (29%), +7pter-q22 (25%), +8q21 (21%), and -6q16–21(25%). Transformed DLBCL showed significantly more alterations as compared to follicular lymphoma (P=0.0001), and the alterations -6q16–21 and +7pter-q22 were only found in transformed DLBCL but not in follicular lymphoma (P=0.02). Alterations involving +13q22 were significantly less frequent, whereas -4q13–21 was more common in transformed as compared to de novo DLBCL (P=0.01 and P=0.02, respectively). Clinical progression from follicular lymphoma to transformed DLBCL is on the genetic level associated with acquirement of increasing number of genomic copy number changes, with non-random involvement of specific target regions. The findings support diverse genetic background between transformed and de novo DLBCL.

High expression of microRNA-200c predicts poor clinical outcome in diffuse large B-cell lymphoma

- Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of B-cell lymphomas. A new and important tool for understanding the biology and clinical course of DLBCL is microRNA expression. This study presents microRNA-200c expression data from 61 DLBCL patients treated with CHOP or R-CHOP. Patients with high microRNA-200c expression had a median survival of 20.3 months and a significantly shorter overall survival (P=0.019) compared to patients with low microRNA-200c expression, who had a median survival of 35.8 months. We also found that patients treated with R-CHOP only and displaying high microRNA-200c expression had a significantly shorter overall survival compared to patients with low microRNA-200c expression, where all patients were still alive at the time of the last follow-up (P=0.0036). Lastly, we found that patients with high microRNA-200c expression had a significantly shorter time from initial diagnosis to the first relapse compared to patients with low microRNA-200c expression (P=0.0001). To our knowledge, this is the first study showing that the expression of microRNA-200c affects the clinical outcome of DLBCL patients, and that microRNA-200c is involved in the biology of DLBCL development, although larger studies are necessary to confirm this. Further investigations may also help to elucidate the biological role of microRNA-200c in DLBCL.

Forskningsöversikt (refereegranskat)abstract
- Aim:To analyze follicular lymphoma (FL) patients by determining the genotype at SNP rs10484561 (T or G) and comparing the polymorphism with overall survival, time to transformation, time from transformation to death, and age both dependently and independently of gender.Materials & methods:A total of 94 patients with FL diagnosed between 1970 and 2000 from a Swedish population were analyzed by PCR–restriction fragment length polymorphism to determine genotypes for rs10484561.Results:We found that women with FL and the TT genotype of SNP rs10484561 were older at diagnosis, transformation and when they died (p = 0.03, 0.01 and 0.02, respectively) and had a significantly shorter overall survival (p = 0.04) compared with women with the TG or GG genotypes.Conclusion:It is possible that the SNP rs10484561 polymorphism is responsible for differences in age at diagnosis, transformation and death for patients with follicular lymphoma, particularly in women.
